Abstract

The invention discloses a numerical control planing and polishing combined machining method for special-shaped blades of a super-huge type water ring vacuum pump impeller and equipment. The numericalcontrol planing and polishing combined machining method comprises the steps that firstly, a special-shaped blade blank is clamped through a blade convex surface positioning clamp, a machining numerical control program is written into a gantry numerical control planer, a thin-wall complex spline molded line variable-thickness blade convex surface is machined by using a circular planer tool, and thecircular planer tool is replaced with a polishing wheel to polish the thin-wall complex spline molded line variable-thickness blade convex surface; and the special-shaped blade blank is clamped by using a blade concave surface positioning clamp, a numerical control program is written into a gantry numerical control planer, a thin-wall complex spline molded line variable-thickness blade concave surface is machined by using the circular planer tool, the circular planer tool is replaced with the polishing wheel to polish the thin-wall complex spline molded line variable-thickness blade concave surface therefore the numerical control planing and polishing combined machining process of the special-shaped blade blank is completed, the machined special-shaped blade blank is cut through a laser cutting machine, and of the multiple special-shaped blades are obtained.

Description

technical field [0001] The invention belongs to the technical field of water ring vacuum pumps, and in particular relates to a numerically controlled "planing and polishing" composite processing method and equipment for special-shaped blades of impellers of extra-large water ring vacuum pumps. Background technique [0002] The water ring vacuum pump is equipped with an eccentrically arranged impeller with fixed blades inside. The impeller converts mechanical energy into kinetic energy of water through rotation to form a rotating water ring. The incompressible rotating water ring and the eccentrically arranged impeller form an air chamber with variable volume to generate pressure. The change achieves the purpose of vacuuming. Due to the advantages of isothermal compression of gas, the water ring vacuum pump is widely used in the coal mine gas extraction system as a fluid machine for transporting gas. [0003] As the depth of coal seam mining continues to deepen, the gas cont...
